BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 724,371, dated MarchApplication filed May 24,1902. Serial N 108,857. (No model:)

To all whom it may concern:

Be it known that I, EDWARD F. ABBEY, of Toledo, in the county of. Lucas,State of Ohio, have invented certain new and useful Improvements inBrush Machines; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

This invention relates to improvements in machinery used in theformation of brushes, and especially in machinery used in the formationof brushes having what are known as solid backs-that is to say, in whichholes are drilled in a brush-block at the proper distances apart and atthe proper angles for the reception of the bristles, and the bristlesare subsequently inserted in said holes and held by means of metallicretainers-although, as will presently appear, the invention made thesubject-matter of this application is capable of a much wider range ofusefulness and may be employed to advantage in connection with anydesired type of machine wherein the brush-block may be positionedautomatically, either for the insertion of the bristles or for theformation of the holes for the reception of the bristles.

The invention consists, therefore, primarily in an improved mechanismfor automatically positioning the brush-block. The invention furtherconsists in certain novel details of construction and combina: tions andarrangements of parts, all as will hereinafter be described, and pointedout particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a side elevation ofa machine embodying my present improvements, portions of the frame andmechanism being shown in section and broken away to disclose under- Fig.2 is a top plan view of a brush-block carrier. Fig. 3 is 'a frontelevation of the same, showing the upper end of the adjusting-shaft.tional view showing a portion-of the mechanism for turning the adjacentshaft on its longitudinal axis. Fig. 5 is a perspective view showingdetails of the mechanism for controlling the horizontal adjustment ofthe block-carrier. r

Fig. 4 is a detail sec-v Like letters of reference in the several figures indicate the same parts.

In illustrating my present invention I have shown it in connection witha machine for insertingbristles or tufts into the brush-block, the typeof machine illustrated being one now in extensive public use and knownas the Gane filling-machine. This type of ma chine is well illustratedin United States Let ters Patent No. 378,130, granted to J. V. GaneFebruary 21, 1888; but it will be understood that the invention may beused in connection with any other desired type of machine,

either for inserting the bristles or having a drill or drills forforming the holes into which the bristles are inserted.

-In the Gane machine illustrated the letters A and A indicate the mainframe of the machine, in which all of theworking parts are mounted; B,the inserter; C, the inserteroperating lever; D, the adjustablebristlesupport; E, the reciprocatory base for the block-carrier, and F Fthe mechanism for reciprocating said base from the main shafts G and G.

, In this machine the block has heretofore been positioned by hand, soas to present its face in proper position and at the proper angle forthe insertion of the bristles; but in accordance with my presentinvention I now propose to position the block automatically by animproved mechanism, thereby relieving the operator of this labor andinsuring a presentation of the block at a mathematicallycorrectangle andin correct position to insure thevbristles 1n the completed brush beingheld in proper relation to each other and to the block-back. Toaccomplish this desirable end, the block or brush-back is held in acarrier mounted on suitable centers having axes at substantially rightangles to each other and capable of an adjustment to vary the radius orare described by the block or back, with a controlling mechanismoperating through a single connection and i embodying pattern disks orcams, which will so move the controlling mechanism as to properlyposition the block. In said drawings the block-carrier is indicated bythe letter H and preferably consists of a rectangular frame havingsuitable clamps h mounted to slide therein andadjustable toward andfromoeach other by means of a screw-shaft H having right and leftthreads thereon and controlled by a rearwardly-extending arms or rods I,adjustably mounted in trunnions r1, taking pivotal hearings in atransverse head or frame K, the arrangement being such that the carrier,with'its block, is free to swing vertically with its block on thetrunnions t'. The head or frame K is provided with a centralrearwardly-extending stem 70, adjustably mount ed in a trunnion L, whichlatter pivots in a bearing L, formed or mounted on the forward end ofthe reciprocatory base or slide E, before referred to. The axis of thetrunnion L is at right angles to the axis of the trunnion t, and byadjusting the stems or rods I or it in their trunnions it is obviousthat the curvature of thearc or arcs described by the face of thecarrier or block mounted therein may be varied at will, and inasmuch asin practically all brushes the curvature of the are on the longerdiameter of the face of the brush is less than the curvature on theshorter diameter the trunnion L is located some distance'in the rear ofthe trunnions t, and in the particular embodiment illustrated in thedrawings the longest diameter of the brush, block will be substantiallyhorizontal, al-

I though it is obvious that this is an arbitrary neetion between thetrack or way being arrangement and is not a necessary incident to thepresent invention.

The control or adjustment of the carrier H is secured through the mediumof a verticallymovable and horizontallyrotatable shaft M, having at itsupper end a crank M, provided with a track or way m, pivotally mountedthereon and extending horizontally or in the line of reciprocatorymovement of the carrier H. This track or way m is adapted to cooperatewith or receive a block N, mounted on the carrier H, so as to be capableof sliding on the track or way, the conpreferably formed by dovetailingone into the other, so as to hold the carrier and shaft M againstindependent vertical movement, as will be understood from an inspectionof Fig. 3 of the drawings. The block N is adjustably connected with thecarrier H, the adjustable connection shown being a conventional one,consisting of angle-irons N secured to the carrier by set-screws Npassing through slots N in the angle-irons, so as to accommodate blocksof different thickness or to increase or diminish the distance betweenthe rows of holes on the face of the block, thereby permitting of themaking of larger or smaller brushes with the same pattern-disk,

vertically the carrier H will be swung on the trunnions 't', and if saidshaft be rotated it will, through the crank M and track,as aforesaid,swing the carrier H horizontally on the trunnion L, and in any of itspositions of adjustment the said carrier H is free to recipro catehorizontally. Thus it is only necessary to provide a means whereby theshaft M may be given the desired movements to accurately position thebrush-block for the operation of the cooperating member. To secure thesemovements of the shaft M and carrier H, I provide a pair of patterndisks or cams P P, Fig. 1, journaled on a center 19 and adapted to berotated intermittently by means of a worm p, a pawl and ratchet p and adriving-camp", mounted on the main shaft G and operating throughaconnection 10 (the end of which surrounds the cam, so as to providecontacting-surfaces therefor) to operate the worm and pattern-disks atthe proper time, or' when the carrier H and inserter B or equivalentcooperating members are retracted from the operative position. Restingon the pattern-disk P is the forward end of an arm R, pivotallysupported on a shaft R and adapted at its forward end to directlysupport the shaft M. Thus as the disk P is retated the shaftM will beraised or lowered, in accordance with the contour outlines of the diskP. A second arm S, eorrespondingto the arm R, rests on the pattern-diskP, this arm S being also pivotally supported on the shaft R and at itsforward end is connected by a link 8 with a bell-crank lever S, pivotedon a portion of.the main frame. The opposite arm of the bell-crank leverS is pivotally connected by a link T with a lever T, the axis of whichis formed by the shaft M, but the support for which is formed by abracket S on the main frame. The outer end of this lever T embraces arod U, which is connected with the shaft M, so as to form a crank,whiehwhen the lever T is oscillated or moved on its axis will rotate theshaft M to a corresponding degree. The connection between the lever Tand crank U is preferably formed by a ball-bearing U, which will permitthe crank or rod U and shaft M, which is jour naled in the bracket S onthe main frame, to move vertically without obstruction, but will holdsaid shaft M accurately in its angular position of adjustment, dependentupon the position of the lever T as controlled, by the pattern-disk P.In mechanism of this character it is desirable that the arms or partscontrolling the position of the carrier II should be lifted out ofcontact with the pattern disk or disks during the feeding movement orrotation of the disks,- and this is especially desirable where sharpchanges in the contour outlines ofv the disks occur and where, as in thepresent instance, it is foundcarriers V carry pawls W, adaptedto engagethe ratchet-wheels V V whenever the carriers V are moved rear-wardly bythe cam V and when so moved to lift the arms R and S out of contact withthe pattern-disks. The cam V operates just in advance of the cam 9 whichrotates the pattern-disks. 0am V is so constructed that it allows thepawls W to move forwardly far enough to insure the lowering of arms Rand S on the patterndisks P P, so as to position the carrier Haccurately at each operation. The controlling-springs X are adjustableon the rods V in position to engage the rear ends of the pawls W andhold them from again engaging the ratchets V V on the rearward motionuntil they have passed the desired number of teeth to overcome theirregularities of the pattern-disks P P. I 7

To secure a wide range of adjustment, the link V may be adjustablyconnected with the lever V as shown in Fig. 1, and,-further more, thelink T, Fig. 4, is also preferably adjustably secured to the lever T, asillustrated clearly in Fig. 4, by a set-screw T whereby the distancebetween the holes in a row may be varied for large or small brusheswhile using the same pattern-disk.

With the mechanism thus described itwill be seen that absolutelyaccurate and uniform results may be secured in the completed brushes andwhat is of greater importance the entire operation so far as thepositioning of the brush-block is concerned is automaticallyaccomplished. As in said Gane; machine, in order to start the mechanismthe operator places his foot on the treadle Z and depresses the same;but inasmuch as in the present embodiment it is desirable that themachine should be automatically stopped when the pattern-disks have madea complete revolu-' tion a stop mechanism ispreferably introduced, whichwill be controlled by the pattern-disks on their shaft. Obviously anywellknown or preferred stop mechanism maybe employed, and I have shown aconventional mechanism consisting of a catch Z, held forward by a springin position to catch and hold the treadle depressed when once pusheddown by the operator, and this catch is adapted to, be automaticallyreleased, so as to allow the treadle to rise and stop the mechanism, bymeans of a projection Z (shown in Fig. 1) on the shaft 19. Theprojection Z pushes downwardly on a rod Z and through a bell-crank Z androd Z releases the catch Z when the pattern-disks have made a completerevolution.
